Google Maps: Auto close open InfoWindows?

On my site, I'm using Google Maps API v3 to place house markers on the map.

The InfoWindows stay open unless you explicitly click the close icon. Meaning, you can have 2+ InfoWindows open at a time if you hover over the map marker.

Question: How do I make it so that only the current active InfoWindow is open and all other InfoWindows are closed? Meaning, no more than 1 InfoWindow will be open at a time?

Create infowindow and just change its content without needing to keep track of an open one, etc.

var map;
var infowindow = new google.maps.InfoWindow();
...
function createMarker(...) {
var marker = new google.maps.Marker({
     ...,
     descrip: infowindowHtmlContent  
});
google.maps.event.addListener(marker, 'click', function() {
    infowindow.setOptions({
        content: this.descrip,
        maxWidth:300
    });
    infowindow.open(map, marker);
});

There is a close() function for InfoWindows. Just keep track of the last opened window, and call the close function on it when a new window is created.

Here is what I used if you are using many markers in a for loop (Django here). You can set an index on each marker and set that index every time you open a window. Closing the previously saved index:

markers = Array();
infoWindows = Array();
var prev_infowindow =false;
{% for obj in objects %}
var contentString = 'your content'
var infowindow = new google.maps.InfoWindow({
            content: contentString,
          });
var marker = new google.maps.Marker({
               position: {lat: {{ obj.lat }}, lng: {{ obj.lon }}},
               map: map,
               title: '{{ obj.name }}',
               infoWindowIndex : {{ forloop.counter0 }}
          });
google.maps.event.addListener(marker, 'click',
            function(event)
            {
           if( prev_infowindow ) {
               infoWindows[prev_infowindow].close();
                }
                prev_infowindow = this.infoWindowIndex;
                infoWindows[this.infoWindowIndex].open(map, this);
            }
        );

        infoWindows.push(infowindow);
        markers.push(marker);

      {% endfor %}

Declare a variable for active window

var activeInfoWindow;

and bind this code in marker listener

 marker.addListener('click', function () {
    if (activeInfoWindow) { activeInfoWindow.close();}
    infowindow.open(map, marker);
    activeInfoWindow = infowindow;
});

var contentString = "Location: " + results[1].formatted_address;    
google.maps.event.addListener(marker,'click', (function(){ 
    infowindow.close();
    infowindow = new google.maps.InfoWindow({
        content: contentString
    });
    infowindow.open(map, marker);
}));

alternative solution for this with using many infowindows: save prev opened infowindow in a variable and then close it when new window opened

var prev_infowindow =false; 
...
base.attachInfo = function(marker, i){
    var infowindow = new google.maps.InfoWindow({
        content: 'yourmarkerinfocontent'
    });

    google.maps.event.addListener(marker, 'click', function(){
        if( prev_infowindow ) {
           prev_infowindow.close();
        }

        prev_infowindow = infowindow;
        infowindow.open(base.map, marker);
    });
}

I stored a variable at the top to keep track of which info window is currently open, see below.

var currentInfoWin = null;
google.maps.event.addListener(markers[counter], 'click', function() {      
    if (currentInfoWin !== null) {
        currentInfoWin.close(map, this); 
    }
    this.infoWin.open(map, this); 
    currentInfoWin = this.infoWin;  
});

How about - 

google.maps.event.addListener(yourMarker, 'mouseover', function () {
        yourInfoWindow.open(yourMap, yourMarker);

    });

google.maps.event.addListener(yourMarker, 'mouseout', function () {
        yourInfoWindow.open(yourMap, yourMarker);

    });

Then you can just hover over it and it will close itself.

There is a easier way besides using the close() function. if you create a variable with the InfoWindow property it closes automatically when you open another. 

var info_window;
var map;
var chicago = new google.maps.LatLng(33.84659, -84.35686);

function initialize() {
    var mapOptions = {
        center: chicago,
        zoom: 14,
        mapTypeId: google.maps.MapTypeId.ROADMAP
    };
    map = new google.maps.Map(document.getElementById("map_canvas"), mapOptions);

    info_window = new google.maps.InfoWindow({
        content: 'loading'
    )};

createLocationOnMap('Location Name 1', new google.maps.LatLng(33.84659, -84.35686), '<p><strong>Location Name 1</strong><br/>Address 1</p>');
createLocationOnMap('Location Name 2', new google.maps.LatLng(33.84625, -84.36212), '<p><strong>Location Name 1</strong><br/>Address 2</p>');

}

function createLocationOnMap(titulo, posicao, conteudo) {            
    var m = new google.maps.Marker({
        map: map,
        animation: google.maps.Animation.DROP,
        title: titulo,
        position: posicao,
        html: conteudo
    });            

    google.maps.event.addListener(m, 'click', function () {                
        info_window.setContent(this.html);
        info_window.open(map, this);
    });
}

//assuming you have a map called 'map'
var infowindow = new google.maps.InfoWindow();

var latlng1 = new google.maps.LatLng(0,0);
var marker1 = new google.maps.Marker({position:latlng1, map:map});
google.maps.event.addListener(marker1, 'click',
    function(){
        infowindow.close();//hide the infowindow
        infowindow.setContent('Marker #1');//update the content for this marker
        infowindow.open(map, marker1);//"move" the info window to the clicked marker and open it
    }
);
var latlng2 = new google.maps.LatLng(10,10);
var marker2 = new google.maps.Marker({position:latlng2, map:map});
google.maps.event.addListener(marker2, 'click',
    function(){
        infowindow.close();//hide the infowindow
        infowindow.setContent('Marker #2');//update the content for this marker
        infowindow.open(map, marker2);//"move" the info window to the clicked marker and open it
    }
);

This will "move" the info window around to each clicked marker, in effect closing itself, then reopening (and panning to fit the viewport) in its new location. It changes its contents before opening to give the desired effect. Works for n markers.

From this link http://www.svennerberg.com/2009/09/google-maps-api-3-infowindows/:

Teo: The easiest way to do this is to just have one instance of the InfoWindow object that you reuse over and over again. That way when you click a new marker the infoWindow is “moved” from where it’s currently at, to point at the new marker.

Use its setContent method to load it with the correct content.
